Managing the development of nurse plant species to improve tree growth and soil fertility in Mediterranean areas
In the Mediterranean basin, overexploitation has lead to the loss of most primeval forests and an increase of the surface area covered by shrublands that represent stages of degradation of mature forests. In this context, huma n intervention is usually necessary to improve recovery of woodlands . Refforestation is a common practice in Mediterranean areas to achieve this objective but its performances are very low with high rates of early mortality making this practice unprofitable in ecological as well as economic terms. In degraded semiarid ecosystems, shrub and tallgrass species grow following a patchy distribution . Traditionally, shrubs growing near to newly planted trees are considered heavy competitors, and consequently removed before planting. However the vegetation patches usually constitute "fertility islands" or "resource islands" which could promote the tree species development. It has been previously assessed that some native plant species could act as "nurse plants " through their positive impacts on soil abiotic characteristics (i .e . soil nutrient contents) but also through their positive influence on soil microbiota, especially on symbiotic microorganisms (rhizobia and mycorrhizal fungi) . The main results showing the beneficial effects of these plant nurses on the growth of Mediterranean tree species (i .e . Cupressus spp. & Piaus halepensis), on the soil bio-functioning are reported and the benefits of using native plant species to rehabilitate degraded areas especially in stressful] conditions are underlined.
